SPECIFICATION forming' part of Letters Patent No. 546,209, dated September 10, 1895..

Application filed December 29, i894, Serial No. 533,331. (No model.)

To all whom t may con/carre:

Be it known that I, CHARLES WILSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Mop-"'Wringeis; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to ro which it appertains to make and use the same.

This invention relates to improvements in mop-wringers, and has for its object to provide a device ofthis character whereby the operation may be mechanically performed,

t5 the same consisting of certain constructive featureszand combinations, as will be hereinafter set forth.

In the drawings, Figure l is a side eleva-t tion, the working parts being in their normal 2o` position; Fig. 2, a sectional elevation, the

working parts being in their opposite position; Fig. 3, a plan; Fig. fi, a horizontal section on line 4, Fig. l,looking in the direction indicated by the arrow; and Fig. 5, a verti-v z5 cal section on angular line 5,'Fig. l.

The tubular supportingframe is composed of a number of pipe-sections, comprising the vertical bars A, the horizontal top bars A', and the base-bars A2, all joined together by 3o the usual connections.

A rotatable movable roll B is journaled in the upper unattached ends of companion levers B B', the lower ends of which lare pivoted, as at c, to the base-bars of the frame at opposite sides. This permits of a reciprocating or swinging movement of the roll B.

The rotatable roll C is provided in the upper part of the frame with journal-bearings c', as shown in Fig. 3. This roll is in a fixed 4c position and has the rotating hand-crank c2 mounted on one end thereof.

A cross'bar b, having its respective ends secured in the frame, has an elbow-sleeve b loosely mounted thereon.

One end of a connecting-link b2 is inserted in an elbow member of sleeve b', the oppo site end connecting with a movable cross-barv A5o The respective upper front edges of levers B B are provided with a triangular camplate d, with which the respective ends of the bar b3 are adapted to have frictional contact.

The upper end ot' a foot-treadle lever D is 55 inserted in an elbow member of sleeve ZJ', the lower end stopping short ot the licor and provided with a foot-plate d. The cross-bar b3 and the foot-treadle lever are connectedA by a pair of braces d2. 6e

VThe guards g g serve the purpose ofV pre venting the edges or strands of the mop from getting in between the reciprocating roller and the frame.

The foot-treadle lever and the cross-bar b3 65 balance on their bea-ring and automatically assume the normal position shown in Fig. l. The rolls are spread apart for the insertion of the mop. W'hen pressure is applied to the treadle-lever, the bar b3, bearing against 7o the cam-plates d, travels upwardly along the inclined edges of said plate and throws the movable roll and the' upper ends of the companion levers, in which the same is journaled, into the position shown in Fig. 2, bringing the two rolls together in compressing an object therebetween.

The water expressed from the mop is received into the fixed pan-receptacle E, from the spout end h of which it is discharged into 8o a pail or other vessel.

In operation the mop is inserted in and compressed between the rolls and the rolls rotated by means of the hand-crank, which has the eiect of expressing the water without the necessity ot' wetting the hands or running therisk of injuring the saine by coming in contact with pins, pieces of glass, pens, or matter of a similar character that is usually 'picked up by the mop. The pressure or" the 9o rolls is regulated by the power applied to the toot-lever.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

l. In a mop-wringer7 the combination of a supporting frame, companion levers, pivoted at their lower ends to the frame and loose at their upper ends, a rotatable roll, journaled in the loose ends of said levers and moving loo therewith, a stationary cross-bar, a movable crossbar, the respective ends of which bear against the companion levers, a link, connectsleeve loosely mounted thereon, a movable ing said cross-bars, a foot-treadle-lever, hav- Gross-bar, a link, connecting said bars, afooting a pivotal connection with the stationary lever, having one end inserted in said sleeve, cross-bar, and a rotatable roll, occupying a and a rotatable roll, journaled in the frame I5 fixed position, substantially as described. substantially as described.
